Weekly Quiz Competition

Question 1
1 / -0

Which of the following is a species?

A
Tamarindus

B
Indicus

C
Indica

D
Tamarindus indica

Solution

According to binomial nomenclature, as first implemented by C. Linnaeus, each species is assigned two names, the first generic names and second species epithet. Tamarindus is a generic name and indicus/indica are specific epithet. As the generic name is mostly a proper noun, it is written with the first letter capitalised while the species epithet is objective and is written in small letters only. Thus, option D is the correct answer.
Question 2
1 / -0

"Théorie élémentaire de la botanique" is the book of

A
Takhtajan

B
Augustin Pyramus de Candolle

C
Eichler

D
Linnaeus

Solution

Augustin Pyramus de Candolle published his 'Théorie élémentaire de la botanique' (Elementary Theory of Botany) in 1813, which introduced a new classification system and the word taxonomy.
Question 3
1 / -0

According to Oswald Tippo, Angiosperms are placed under

A
Atracheata

B
Thallophyta

C
Tracheophyta

D
Spermatophyta

Solution

Oswald Tippo, University of Illinois 1942, classified plant kingdom into two sub-kingdom; Thallophyta (thalloid plant body without distinct alternation of generations and no embryo) and Embryophyta (organ level differentiation of plant body with regular alternation of sporophyte and gametophyte generations and embryo present). Since, algae and fungi lack embryo, they are placed in sub-kingdom Thallophyta which makes option B incorrect. Sub-kingdom embryophyta includes Bryophyta/Atracheata (dominant gametophyte generation and absence of vascular tissues) and Tracheophyta (sporophyte dominant with advanced vascular tissues). Option A is incorrect as Atracheata includes non-vascular plants while angiosperms are vascular plants. Tracheophyta includes four subphyla, these are namely Psilosida, Lycopsida, Sphenopsida and Pteropsida. Pteropsida includes three classes: Filicinae (ferns), Gymnospermae (gymnosperms) and Angiospermae (angiosperms) which makes option C correct. The group “Spermatophyta” was not mentioned in his classification which makes option D incorrect. Thus, the correct answer is option C.
Question 4
1 / -0

"Genera Plantarum'' was written by

A
Engler and Prantal

B
Hutchinson

C
Carl Linnaeus

D
Bessey

Solution

Swedish naturalist Carl Linnaeus published book Genera Plantarum. The first edition of Genera Plantarum was issued in Leiden in 1737 which contains brief descriptions of the 935 plant genera.
So, the correct answer is option C.
Question 5
1 / -0

Oswald Tippo included how many divisions in sub-kingdom thallophyta?

A
20 divisions

B
10 divisions

C
7 divisions

D
2 divisions

Solution

Oswald Tippo, University of Illiniois 1942, classified plant kingdom into two sub divisions; Thallophyta (thalloid plant body without distinct alternation of generations) and Embryophyta (organ level differentiation of plant body with regular alternation of sporophyte and gametophyte generations). The sub-kingdom thallophyta was divided into 10 phyla/divisions: Cyanophyta (Blue green algae), Euglenophyta (Grass green algae), Chrysophyta (Yellow green algae), Chlorophyta (Green algae), Pyrrophyta (Golden brown algae), Phaeophyta (Brown algae), Rhodophyta (Red algae), Schizomycophyta (Bacteria), Myxomycophyta (Slime molds) and Eumycophyta (True fungi). Thus, the correct answer is option B.
Question 6
1 / -0

Botanical name of bajra is

A
Triticum aestivum

B
Pennisetum glaucum

C
Zea mays

D
Sorghum vulgare

Solution

Pearl millet or bajra (Pennisetum glaucum) is the most widely grown type of millet. It has been grown in Africa and the Indian subcontinent since prehistoric times. The centre of diversity and suggested area of domestication for the crop is in the Sahel zone of West Africa. Because of its tolerance to difficult growing conditions, it can be grown in areas, where other cereal crops, such as maize or wheat, would not survive. Thus, the correct answer is option B.
Question 7
1 / -0

Bacteria and yeast are similar to each other in all of the following characteristic, except that

A
Both are capable of causing fermentation

B
Both have cell wall

C
Both are prokaryotes

D
Both are unicellular

Solution

1. Bacteria and yeast both are able to perform fermentation as widely used in industries
2. Bacteria and yeast both are unicellular in nature and have a cell wall
3. Bacteria is a prokaryote placed under monera kingdom whereas yeast is a eukaryote placed under the kingdom Fungi
So the correct option is 'Both are prokaryotes'.
Question 8
1 / -0

Evolutionary history of an organism is known as

A
Ontogeny

B
Phylogeny

C
Ancestry

D
Paleontology

Solution

The evolutionary development and history of a species or trait of a species or of a higher taxonomic grouping of organisms is known as phylogeny
So, the correct answer is 'Phylogeny'
Question 9
1 / -0

Botanical name of potato is

A
Solanum tuberosum

B
Manihot esculenta

C
Malus pumila

D
Piper nigrum

Solution

The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum L. The word "potato" may refer either to the plant itself or the edible tuber. Thus, the correct answer is option A.
Question 10
1 / -0

In nature, the biologically cohesive unit among the taxa is

A
Genus

B
Order

C
Phylum

D
Species

Solution

A biologically cohesive unit is the group of the organism which can interact among themselves and is able to produce fertile offsprings. Species are considered as a biologically cohesive unit because they can interbreed among themselves and can produce fertile offsprings
So, the correct answer is 'Species'
